of sous vide cooking pleasure.

IMPORTANT
This instruction manual contains information for the use and maintenance of your Wartmann® sous
vide device. Read this instruction manual carefully before using the Wartmann® sous vide device and
keep it for possible later consultation.
Requires regular upkeep
This Wartmann® sous vide device is designed for (semi)-professional use and should be regularly
descaled. In case of incorrect use, usage not in accordance with the instructions in the manual, or self-
performed repairs, the warranty expires and Wartmann® will decline any responsibility for any damage
caused by this.
People with disabilities
The Wartmann® sous vide device can be used by persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have been given supervision or instruction
concerning the use of the Wartmann® sous vide device in a safe way and if they understand the hazards
involved.
Check electrical connections
Check if the voltage indicated on the Wartmann® sous vide device conforms to the local mains voltage
before connecting the Wartmann® sous vide device. Connect the Wartmann® sous vide device
exclusively to a grounded socket. In case the plug, power cord or the Wartmann® sous vide device
itself is damaged, repairs must be carried out first or the relevant part should be replaced by a qualified
service centre.
Prevent water from getting into contact with electrical parts
The Wartmann® sous vide device contains electrical parts and heating elements. To avoid danger, the
power cable, power socket, fan outlet and control panel should not come into contact with water.
Make sure that no water ever enters the Wartmann® sous vide device, other than the water basin, to
prevent electrical shock and/or damage to the Wartmann® sous vide device.
Contains heating elements
The water inside the Wartmann® sous vide device may be hot. The water temperature is indicated at
the display. Do not touch the hot water to avoid burns. In case of doubt use a thermometer to check
the water temperature. Use plyers to remove vacuum bags from the hot water. Also avoid getting into
contact with the hot surfaces during or after use to avoid burns.
Do not position the Wartmann® sous vide device near flammable materials (such as curtains) or
cleaning agents (such as methylated spirit).
Maintain proper water levels
During use the water level in the water basin should be kept between the lowest water level "MIN"
and the highest water level "MAX" indicators to avoid damaging the machine.
Use original accessories
This manual applies to the optional use of Wartmann® accessories. For accessories from other
suppliers, other instructions may apply.

USING THE SOUS VIDE DEVICE
Unpacking the sous vide device and preparations for first use
Take the Wartmann® sous vide device out of the box and remove all packaging materials. Place the
Wartmann® sous vide device on a horizontal surface in a location. Check that the power switch at the
back is easy accessible. Mount the rack on top of the tray and place the combination inside the water
basin.
Insert the power cable into the power socket at the back of the Wartmann® sous vide device, then
plug the power cable into a grounded socket.
Switching on the sous vide device
Fill the water basin with water. The water level should be between the “MIN” and “MAX” indicators
imprinted inside the water basin. Note that the water level may rise when placing the vacuum bags,
therefore always leave enough free space to compensate for the volume of the vacuum bags.
Optionally place the lid on top of the Wartmann® sous vide device.
Flip the power switch at the back of the Wartmann® sous vide device. The temperature display will
now show the text “OFF”. Your Wartmann® sous vide device is now ready for use.
Set time and temperature
Press ]> to switch to standby. The temperature display [D] will show the last set water temperature;
the time display [E] will show the last set time.
Press the up- and down arrows to set the required time and temperature. Press [SET] to switch
between setting the time and the temperature.
To change the temperature unit from the default Celsius to Fahrenheit, or vice versa, press the up- and
down arrows simultaneously.
Start Cooking
Verify that the vacuum bags are properly sealed and not punctured. Place the vacuum bags in the
water basin, check that the water level is not above the “MAX” indicator, and close the lid.
Press ]> to start cooking. The Wartmann® sous vide device is now operational and the displays will
show the actual temperature and remaining time.
Finish Cooking
Once the cooking is finished - the remaining time is zero –the Wartmann® sous vide device will beep
every 20 seconds. Lift up the lid and take the vacuum bags out of the water basin. You may need to
use plyers to avoid getting burned. Process the vacuum bags further as required by your recipe.
Press ]> to switch back to standby. Otherwise the beep will repeat every 20 seconds for 30 minutes
while the water is kept at the set temperature.
Another cooking
Another cooking cycle can be started immediately by placing the next set of vacuum bags and pressing
the ]> button.

AFTER USE
Switch-off
Switch the Wartmann® sous vide device off with the power switch after use. To avoid premature aging
of the Wartmann® sous vide device the water should be drained and the water basin cleaned.
Cleaning
Let the water cool off to room temperature before cleaning. Unplug the power cord from the wall
socket. Place a large bucket under the drainage tap and drain the water. Carefully take out the rack
and tray out by slowly lifting at the handles at both sides.
Clean the water basin, the tray and rack and any other accessories. Dry with a soft cloth and put the
accessories back in the water basin for storage. Make sure not to damage any inner parts when
cleaning the Wartmann® sous vide device.
Storing
Once the water basin and accessories are clean and dry the Wartmann® sous vide device may be stored
horizontally. Do not store the Wartmann® sous vide device upside down.
Maintenance
The Wartmann® sous vide device must be descaled regularly and at least after every hundred hours of
usage. For hard water descaling may be required more frequently. See the paragraph on descaling.
For an optimal lifespan of your Wartmann® sous vide device, we recommend to not fill a hot
Wartmann® sous vide device with cold water, or to fill a cold Wartmann® sous vide device with hot
water.
The water in the water basin should be frequently refreshed. We recommend to replace the water on
a daily basis.

DESCALING
Why descaling
Tap water contains minerals such as Calcium and Magnesium. Heating this water results in scale
deposits on the thermostat and the heating element of the sous vide machine. As a result the heater
may not work efficiently and the water pump may get blocked. The Wartmann® sous vide device
should therefore be descaled regularly. The frequency with which you need descaling depends on the
hardness of your tap water. We recommend to descale the Wartmann® sous vide device after every
100 hours, or after every 20 times, of use.
Tools
To descale the Wartmann® sous vide device you will need a suited descaling agent. You may use a food
save (white) vinegar or citric acid as a descaling agent. Check the recommended temperature for your
descaling agent before usage.
Descaling process
Fill the water basin with water just up to the “Max”indication, leaving enough space to add the
descaling agent. Add the descaling agent. For vinegar, add 15 grams of vinegar. Wear protective
clothing when working with chemicals, use rubber gloves and safety glasses. Rinse immediately with
clean water if undiluted chemicals get into your eyes; if necessary contact your doctor.
Plug the power cord into the power socket and switch the Wartmann® sous vide device to standby.
Set the duration at 3 hours and the temperature at 80℃(176 F).
Press ]> to start the descaling process. After 3 hours you will hear a beep tone.
Press ]> to switch the Wartmann® sous vide device in standby. Switch the Wartmann® sous vide device
off and remove the power cord from the power socket.
Check the device for any signs of remaining scale. Repeat the above cleaning cycle if scale is still
present; if necessary add more descaling agent.
If there are no more signs of scale then please a bucket under the drainage tap and drain the water
basin. Rinse the water basin and accessories with clean water.
If the water filters at the bottom of the water basin are blocked, then they can be unscrewed, removed
and cleaned. Do not forget to screw the water filters back in place.

RECYCLING THE SOUS VIDE DEVICE
If the Wartmann® sous vide device is at the end of its life cycle, you can deliver it to a collection point
for the recycling of electrical equipment. The Wartmann® sous vide device should not be disposed of
along with regular household rubbish.
